Why is the array not sorted by "insertions" method?

Question

C++ / C#

Why is the y array not sorted? It is necessary by the "inserts" method.

#include<iostream>
#include <cstring>
#include<cmath>
#include<cstdlib>
#include<conio.h>
#include<ctime>
#include<windows.h>


using namespace std;

int main()
{
  setlocale(LC_ALL, "");
  const int n = 5;
  int x[n], y[n], i, j, temp, max = -1000, min = 1000, a, b;
  cout << "Введите 2 значения для вычесления = " << endl;
  cin >> a;
  cin >> b;
  cout << "Массив x " << endl;
  for (int i = 0; i < n; i++)
  {
    x[i] = rand() % 20 - 10;
    cout << "x[" << i << "] = " << x[i] << endl;
  }
  cout << endl;
  for (i = 0; i < n; i++)
  {
    y[i] = a / x[i] - b / sin(pow(a, 2.0));
    if (y[i] > max)
    {
      max = y[i];
    }
    if (y[i] < min)
    {
      min = y[i];
    }
  }
  for (i = 0; i < n; i++)
  {
    temp = y[i];
    for (j = i - 1; j >= 0 && y[i] > temp; j--)
    {
      y[j + 1] = y[j];
      y[j + 1] = temp;
    }
  }
  for (i = 0; i < n; i++)
  {
    cout << "y [ " << i << " ] = " << y[i] << endl;
  }
  cout << "Минимальное значение массива = " << min << endl;
  cout << "Максимальное значение массива = " << max << endl;

  system("PAUSE");

}

Doesn't anything bother you in these two consecutive lines?

y[j + 1] = y[j];
y[j + 1] = temp;
